2. Olivier MartinThe BETEL Project 28/11/1997 Slide (2) Background u Call for Proposals issued by European Parliament (1992): l Demonstration of Interworking Via Optical Networks (DIVON). u Four projects selected: l I2001 - Isabel (Portugal - Spain) l I2002 - Tironet (Ireland) l I2003 - Betel (France - Switzerland) l I2004 - HPC-Vision (France - Germany)

3. Olivier MartinThe BETEL Project 28/11/1997 Slide (3) Key aspects u Very unique collaboration between Telecom Operators, Information Technology suppliers and advanced user communities (High Energy Physics & High Education Institutes). u Small, well focused, project with few partners. u Short duration (12 months).

4. Olivier MartinThe BETEL Project 28/11/1997 Slide (4) Applications u High speed distributed computing: l allow transparent (i.e. location independent) access to shared resources) : »CPU, disk and tape servers. u High quality Tele-Teaching: l conventional (Tele-Amphi). l remote teacher supervising students (application sharing).

5. Olivier MartinThe BETEL Project 28/11/1997 Slide (5) Results u First Trans-European ATM 34 Mb/s links in operation from 9/93 through 12/93. u Seamless access to tape and disk servers located at CERN from IN2P3 (Lyon) achieved on a near-production basis. u Advanced Tele-teaching scenarios demonstrated between EPFL (Lausanne) and Eurecom Institute (Sophia Antipolis).

6. Olivier MartinThe BETEL Project 28/11/1997 Slide (6) Benefits u Telecom Operators : l validation of ATM transport over international optical fiber circuits. l better understanding of advanced applications requirements and services necessary to support these. u Information Technology Industry : l validation of ATM equipment (cross connect, adapters, routers) in a realistic production environment. u Users: l deployment of existing applications over real Wide Area ATM network.

7. Olivier MartinThe BETEL Project 28/11/1997 Slide (7) Follow-on projects (I) u European ATM pilot (1994-1995) and its EU funded successor JAMES (1996-1997): l Broadcasting of some academic training seminars from CERN to Finland. l RACE & ACTS summer school 1995, 1996. u TEN-34 (1997-1998): l Pan-European 34 Mb/s backbone interconnecting National Research Networks. l Two sub-networks, one of which uses ATM in a very similar way to BETEL.

8. Olivier MartinThe BETEL Project 28/11/1997 Slide (8) Follow-on projects (II) u BETEUS (1994-1995): l Tele-teaching part of BETEL expanded to more partners, CERN included, and more aggressive work plan. u STEN (Scientific Trans-European Network) - (1994): l Distributed conferences and Video on Demand (VoD) services.

9. Olivier MartinThe BETEL Project 28/11/1997 Slide (9) Final comments l Back in 1993, Betel was a very advanced project: »Europe was lagging behind the USA with 2 Mb/s international links and little developed national research networks. »Major progress have been accomplished since then (TEN-34, JAMES), in terms of general purpose European networking infrastructure for research. »It is not unreasonable to think that BETEL contributed to these very positive developments. l However, technology is moving very fast: »Today’s requirements are a factor 5-10 higher than in 1993, i.e. 155/622 Mb/s test beds are urgently needed.

10. Olivier MartinThe BETEL Project 28/11/1997 Slide (10) Conclusions u Very unique collaboration between Telecom Operators, Information Technology suppliers and advanced user communities (High Energy Physics & High Education Institutes) with active EU support. u Strong synergy between the actors above, may not be as well exploited in Europe as it is in the USA.
